摘要
铜绿山铜铁矿床位于鄂城-大幕山新华夏复合隆起带中部、阳新复式岩体西北端。矿体赋存于下三叠统大冶群第四至第七岩性段。矿床由12个矿体组成。矿区内岩浆活动频繁。通过对区内岩浆演化、岩石化学、岩性特征以及微量元素特征等方面系统研究,认为矿床成矿物源为铜绿山石英正长闪长玢岩岩体,含碱值偏高的中酸岩类是控制成矿元素富集及各类矿床组合的内在因素,岩浆的成矿专属性由岩浆本身特性决定。
The Tonglushan Cu-Fe deposit is located at the middle part of the Neocathaysian compound mole track and the northwestward of the Yangxin complex massif. The ore-body lies in the third to seventh segment of the Daye group of lower Triassic series. The deposit makes up of twelve ore-bodies. The movements of magma in this diggings are very frequent. Through these aspects, such as magmatic evolution, and lithogeochemical, and lithological features and the characters of microelement, are systemic studied in this diggings, it is proved that the metallogenic matter comes from the Tonglushan quartz syenite diorite porphyrite stock, and the intermediate-acid rock with high alkalinity is the inherent cause in controlling enrichment of metallogenic element and the assembled of various of deposits, and the metallogenic specialization of magmas is decided by the characters of magmas.
